Horizonte CEO Jeremy Martin said, "There is a considerable amount of
activity taking place at the Araguaia Project. We currently have four
drill rigs operating on the infill resource drilling programme with the
aim of completing 7,000 metres of drilling to convert approximately 50
million tonnes of the higher grade material to the Indicated Category.
The drilling at the Jacutinga target was completed in December 2012 and
we are pleased to report a number of high grade intercepts including
23.2 metres grading 2.09% nickel.

"In addition to the resource drilling programme, we have just completed
metallurgical test work with the global leader in high temperature kiln
technology, FLSmidth. The test work was designed to evaluate the
expected ore performance in rotary kiln processing and we are pleased
to report that Araguaia ore was found to be suitable for treatment
using this technology. Rotary kiln processing is a key step in the
well established Rotary Kiln-Electric Furnace pyro-metallurgical
process that we are aiming to utilise at Araguaia. Consequently, the
success of the metallurgical test work marks another major step in
de-risking Araguaia and demonstrates that the ore can be processed
using proven technology. Work is now focused on moving the project
into the pre-feasibility stage and we hope to award the pre-feasibility
study contract in Q1 2013."

Further Details

The drill results have been collated from the Phase 3 mineral resource
drilling programme that commenced in September 2012. This programme is
designed to complete infill drilling on 100 metre x 100 metre grids on
the Jacutinga, Vila Oito, Vila Oito East and Pequizeiro West targets of
the Araguaia Nickel Project in Brazil. To date, 81 holes (2,653
metres) have been completed. The results from 24 holes (808 metres)
from the Jacutinga target received to date are detailed in Table 1. The results contain several wide, high-grade intersections, including
23.2 metres grading 2.09% nickel (Hole PCA-DD-1111). This intersection
includes a continuous length of 10.10 metres grading 2.91% nickel; 9.09
metres grading 2.11% nickel (Hole PCA-DD-1103); 16.1 metres grading
1.73% nickel (Hole PCA-DD-1118) and 14.1 metres grading 1.62% nickel
(PCA-DD-1122).

The compositing of the nickel grades in the individual holes was
completed across geological boundaries using a nickel cut-off of 1%
with a minimum intercept length of 2.0 metres and a maximum length of
internal waste of 2 metres. All holes were vertical and as these nickel
laterite deposits are essentially flat-lying, all widths given are true
widths.

Sample preparation and analyses

Samples from drill core were crushed and pulverised at the SGS
laboratory in Goiania and the resultant pulps analysed at the SGS
laboratory in Belo Horizonte using tetraborate fusion and X-Ray
Fluorescence ('XRF'). Full QA/QC procedures were followed, including
the insertion of standards, duplicates and blanks. Check samples
representing approximately 5% of all the samples, will be sent to
another international laboratory for analysis by XRF.

FLSmidth Kiln Test Work

Two blends of Araguaia laterite were submitted to the laboratories of
FLSmidth (http://www.flsmidth.com) located in Bethlehem, Pennsylvania, USA, for rotary kiln evaluation
testing. The overall results of the study show that Araguaia ore is
suitable for rotary kiln processing; a range of suggested kiln
operating conditions were indicated. The testwork included the
following:

Ore reduction and sintering tests including small scale briquetting
tests.

The determined properties of the two Araguaia blends show that the
material is amenable to high temperature kiln processing. The dry
particle size distribution data and the results of the tumble testing
were found to be generally comparable to those of a number of laterite
ores currently handled in commercial Rotary Kiln-Electric Furnace
operations. The sintering tests established the range of kiln operating
temperatures. In the ore reduction tests, the degree of iron reduction
was considered normal, and while a somewhat lower degree of nickel
reduction was obtained, this result does not materially affect overall
Rotary Kiln-Electric Furnace performance. Some additional metallurgical
testwork is on-going and is expected to be completed during Q1 2013.
This includes a mineralogical study on one of the ore blends tested at
F.L. Smidth, and measurements of the Araguaia slag melting point.

Horizonte Minerals plc is an AIM and TSX listed exploration and
development Company with a portfolio of nickel and gold projects in the
Carajas District of Brazil. The Company is focussed on creating value
by generating and rapidly advancing exploration projects in tandem with
joint ventures with major mining companies, providing mid-term cash
flow, which is then used to develop the business and pipeline projects.

Horizonte has two committed major mining partners: Teck Resources
Limited, a major strategic shareholder in the Company, and AngloGold, a
JV partner on the Falcao gold project.

Horizonte owns 100 per cent of the advanced Araguaia Nickel Project
located to the south of the Carajas mineral district of northern
Brazil. The project has defined a resource with size and grades
comparable to other world-class projects in northern Brazil and the
Company has completed a Preliminary Economic Assessment on the project
which illustrates robust economics based on low strip ratio, good
infrastructure, large mineral resource with two viable alternatives for
processing.

Horizonte is well funded to accelerate the development of its core
project.
